Saunum Air Stainless Open Basket keeps more heat lower in the room. That means you don’t need to climb a ladder to reach the perfect seating position. Of course, this heater does what Saunum is famous for: redistributing the hottest air that settles at the ceiling, mixing it with cooler fresh air and redistributing it at the floor. But the open basket also releases more energy directly through the sides than its solid black counterpart.
That means you’ll get more direct radiant heat and steam directly from the rocks. If you’re looking for a more intense heat that’s evenly distributed, the open basket Saunum Air is for you.
With the external temperature sensor (now shipping free with Sauna Marketplace orders!) the Saunum Air gets hotter than ever. It’s versatile, and a truly world-class sauna experience. Take it from the folks at Sauna Marketplace, it’s hard to go back.
Saunum Air is UL-approved for North America and ships daily out of greater Chicago. At Sauna Marketplace, every Saunum Air package comes with specially selected rocks paired by Saunum, Wi-Fi enabled AirIQ Controller, Himalayan salt spheres, External Temperature Sensor, US-based support, and the latest integrated power box for simplified installation.

Saunum's unlike any other sauna. It's like a sanctuary for wellness and recovery. The moment I step into a Saunum I feel the warmth envelope my body. I start to feel stress and fatigue melt away.
You can really feel the difference thanks to its air blending system. Normally in saunas you can feel cold air at the bottom and much more hot air at the top.
Saunum's air blending technology allows all the air to blend evenly throughout the sauna and it really gives you the best experience you could possibly have without any cold spots or hot spots throughout the sauna. It allows you to breathe deeply and comfortably without experiencing too much fatigue.
Saunum has really transformed the way I experience sauna and has become a real integral part to my personal wellness routine. Saunum isn't just a sauna, it's the perfect sauna.
Electric saunas have one big problem.
Stratification.
Hot air rises and becomes stale without combustion from a wood fire. It’s not uncommon for an electric sauna to be 200 degrees at head height and under 100 degrees at foot height.
The freshest air sits low and the heat collects high, where your head is most sensitive to it.
Saunum says the Air is designed to reduce heat stratification, for more even heat throughout the room.
These state-of-the-art sauna heaters deliver a superior sauna experience, thanks to the patented air blending technology that mixes cooler, fresher air from the floor with the hot air at the ceiling. The result is a more even temperature from head to toe and a more comfortable room.
Saunum Air Series is available in elegant Nordic Black and polished Stainless Steel finishes, a nod to Scandinavian design aesthetics. They come with an adjustable valve for cool air intake, located 12 inches off the floor, and an output for blended air, ensuring perfect air circulation.
The standard Saunum Air comes in two sizes, rated the same for the black closed basket and the stainless open basket: the Saunum Air 5 for 106-212 cu. ft. and the Saunum Air 7 for 177-318 cu. ft. Both run on 240 V single phase and are UL-listed.
The Saunum Air L comes in three larger sizes: the Air L 10 for 283-494 cu. ft., the Air L 13 for 424-565 cu. ft. and the Air L 15 for 530-812 cu. ft.
Glass, tile, stone and uninsulated log walls change the size you need. Saunum adds 3 cu. ft. for every square foot of glass or masonry and multiplies the room volume by 1.5 for uninsulated log walls. If your room lands between two sizes, take the larger one, or contact us and we’ll size it with you.
Each Saunum Air model features a large stone capacity, ranging from 110 lb to 190 lb, producing softer, more even heat. Every model comes with Himalayan salt spheres that sit in the heater’s airflow, and an optional aroma kit adds scent. The Saunum Air Series also offers a Wi-Fi control option for convenience and customizability.
With the Saunum Air Series, you can experience the best of sauna bathing, delivered through innovative technology and elegant design. Transform your sauna sessions with Saunum – it’s all about the air you heat, feel, and breathe.
Note: Saunum Air Stainless body requires 30 inches of clearance on the sides and 20 inches in front of the fan:
Note: Black solid body Saunum Air requires 2" on each side and 20 inches in front of fan.
Saunum Air is the US version of the Saunum primary with UL listings. The tradeoff with UL listings is they require a maximum temperature of 194 degrees Fahrenheit, while European models can be programmed to 230f. However, with air movement and a more evenly heated sauna, you’ll find 194 degrees in the Saunum is a far more envigorating experience than any other heater on the market.
Compared to the solid black finish, the stainless steel rock basket distributes more air from the side of the heater, resulting in greater side clearances and higher minimum ceiling heights. The stainless steel options can handle larger spaces as well.
The minimum ceiling heights are to provide the minimum safety clearances and are not necessarily the physical limitations of the heater.
Yes, the Saunum AIRIQ WiFi upgrade lets you control the Saunum from your phone.
No, the Saunum distributes power to the fan.
We are working on pairing Saunum with our larger SaunaLife and Thermory barrel saunas. It may require a heat shield and other considerations. Please get in touch with us for details.

Before the introduction of the Saunum circulating air heater, Erkka Suominen, a long-time sauna and hockey enthusiast, had a traditional setup in his small apartment sauna with a Harvia Cilindro. "I knew there was room for improvement," Erkka expressed, highlighting his discontent with the uneven heat distribution in his sauna, forcing him to uncomfortably raise his feet to the upper platform for a smoother sauna experience.
In late 2022, Saunologia gave him an opportunity to test out the Saunum circulating air heater, which draws in hot air and moisture from the edge of the ceiling and blows it down to the floor, evening out temperature differences and moving the steam lower in the sauna. The experiment was carried out in November-December 2022, with the heater noticeably improving Erkka's sauna comfort. "Now, I'm able to spend a longer time in the sauna than before," he stated.
A month into the trial, Erkka found that he could create different sauna conditions with the Saunum heater by changing the combination of the sauna room's target temperature and fan strength. After the experiment, he also noted a significant reduction in temperature differences within the sauna, saying, "Before, the temperature difference from the ceiling to the footboard was more than 30 C, but now it's below 15 C."
Six months after the beginning of the experiment, Erkka was delighted with the Saunum air heater's performance. He remarked, "Saunum rocks and is in heavy use." Moreover, he found the Saunum remote control practical, allowing him to turn on the sauna from his phone.
In summary, the introduction of the Saunum circulating air heater significantly improved the sauna experience for Erkka, enhancing the heat distribution and allowing him to spend more time comfortably in the sauna.

Start with the room dimensions, then account for glass, masonry, insulation, ceiling height, required clearances, and available electrical service. That is how we move from a product that looks right to a sauna that heats evenly and comfortably.
